These figures cover 298 flights between September 2025 and August 2026. The median arrival is 2 minutes early, which is the part an average hides: most flights here are fine, and the on-time rate is decided by a tail of badly late ones. On-time means under 15 minutes late, the DOT's own threshold.

Across the year
AS 1394 quarter by quarter
AS 1394 did not run the same all year. Its best quarter was Jan–Mar 2026 at 92.0% on time and its weakest Jul–Sep 2026 at 58.3%, a swing of 34 points on roughly 75 flights a quarter. The twelve-month rate averages over that, so if you are flying in a weak quarter the quarter's own figure is the better guide.

Share of 296 completed flights by arrival against schedule.
A late pushback is often recovered here: of 55 departures that left 15 minutes late or more, 17 still arrived on time. In the other direction, 22 flights left on time yet arrived 15 minutes late or more, so that delay built up after pushback: in the air, in a holding pattern or on the ground at SAN.
The worst days
Worst days for AS 1394
The latest arrival of the period was on 5 January 2026, 2 hours 50 minutes behind schedule; most of its delay minutes were filed as a late-arriving aircraft. The five worst days are spread across January, May, August, December and November, with no single month standing out.
| Date | Arrived late by | Largest filed cause |
|---|---|---|
| 5 January 2026 | 2 hours 50 minutes | Late-arriving aircraft |
| 10 May 2026 | 1 hour 35 minutes | Late-arriving aircraft |

Delay causes
Why AS 1394 runs late
National Airspace System accounts for 66% of the 2,029 delay minutes carriers reported here, and the remaining four split what is left.
- 66%National Airspace System
- 20%Late-arriving aircraft
- 13%Carrier
- 1%Extreme weather
66% of delay minutes are charged to the National Airspace System: air traffic volume, runway configuration, ground stops. No carrier can price its way out of that, which is why airport choice moves the number here more than carrier choice does. That is 1,347 minutes out of 2,029, against a national NAS share of 21%. The split is drawn from 2,029 delay minutes reported on AS 1394.
Cancellations are rare at 0.67%, below the national 1.89% and low enough to earn the plus on the grade. Roughly one flight in 100 is called off; the risk here is arriving late, not not arriving.
Connections and routes
What a delay on this flight costs
Badly late arrivals are rare here: only 1.4% land an hour or more behind schedule, against 8.3% nationally. Connections built on this flight are about as safe as US domestic connections get, though a cancelled flight still ignores every layover you give it.
The 933 miles between these two airports put this in the middle of the US network, around two and a half to three hours of block time. That is enough cruise to absorb a ten-minute late pushback and not enough to absorb thirty.
Every one of the 298 flights under AS 1394 in the data flew PDX to SAN. The number was not reused on any other city pair, which makes this a clean record of one route.
One caution: this is a thin sample. 298 flights over twelve months is enough to clear this site's floor but not enough to pin the rate down tightly, and a single bad week moves it by more than a point. Treat the grade as a rough reading.
What to do with this
Booking AS 1394
For a booking, read AS 1394 as 79.7% on time with 0.67% cancelled over 298 flights. Those are rates from the past twelve months, not a forecast for any particular day.
